A flaw was found in glibc. When processing paths that start with a tilde (~) followed by a username, the `wordexp` function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhaustion and causing a denial of service (DoS) for the affected application.
A flaw was found in curl's cookie parsing logic. A malicious HTTP server can exploit this by setting 'super cookies' that bypass the Public Suffix List check. This allows an attacker-controlled origin to inject cookies that curl then transmits to unrelated third-party domains, leading to compromising request integrity.
A flaw was found in curl. When `libcurl` performs a transfer to an HTTP origin using Digest authentication and then reuses the same connection handle for a subsequent transfer to a different origin, it may incorrectly send the authentication header intended for the first origin to the second. This could lead to unintended information disclosure, potentially allowing an attacker to gain unauthorized access to sensitive data.
A flaw was found in GDB's STABS debug format parser. The read_member_functions() function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main function list while the list length counter is decremented, resulting in an out-of-bounds write when the function list is copied to its final allocated array. An attacker can craft an ELF binary with malicious .stab and .stabstr sections that triggers this out-of-bounds write when a user opens the file in GDB and performs any symbol-inspection operation such as setting a breakpoint. The inferior process does not need to be executed. Under controlled conditions, this was demonstrated to achieve execution of arbitrary commands within the GDB process.
A flaw was found in the GNU C Library (glibc). This vulnerability could allow an attacker with local access to trigger a heap buffer overflow by manipulating how the `fopen` function handles certain input. This could lead to minor disruptions in system operations or limited access to sensitive information.
A flaw was found in Python. A remote, unauthenticated TLS client can cause a use-after-free in a server that uses SSLContext.sni_callback to assign a different SSLSocket.context when selecting a certificate per server name, if nothing else keeps the original SSLContext alive. This can crash the server process or result in a call through a freed pointer. Servers that wrap their listening socket with a long-lived SSLContext are not affected. TLS clients are not affected.

A flaw was found in glibc. An out-of-bounds array write vulnerability exists within the `tdelete` function. This issue occurs due to incorrect management of array sizes, which can lead to memory corruption. A local attacker with low privileges could potentially exploit this to cause a denial of service or disclose sensitive information.
A flaw was found in Python. When establishing secure connections using the SSLContext.wrap_bio() function with hostname checking enabled, the module fails to validate that a target server hostname is supplied. Because of this missing check, certificate hostname verification is silently skipped rather than triggering an error. A remote man-in-the-middle attacker could exploit this defect to spoof trusted endpoints and intercept or tamper with sensitive encrypted traffic.
A flaw was found in gawk. A Use After Free vulnerability exists in the do_getline_redir() routine within the io.c program file. This vulnerability can be triggered by an attacker, potentially leading to a system crash and causing a Denial of Service (DoS).
A flaw was found in gawk. An integer overflow vulnerability could allow a local attacker to cause memory exhaustion, leading to a denial of service. This flaw may also enable an attacker to corrupt gawk's internal memory, potentially leading to system instability.
A flaw was found in gawk. A buffer overflow vulnerability exists in the `ftype()` routine, located in the `extension/readdir.c` program file. This vulnerability could allow an attacker to crash the program, resulting in a denial of service. It may also potentially lead to arbitrary code execution, though this has not been definitively confirmed.
A flaw was found in OpenSSH's SSH daemon (sshd). A remote attacker could exploit this vulnerability by repeatedly attempting authentication. The flaw allows the attacker to bypass the intended minimum authentication delay, which can facilitate brute-force attacks. This makes it easier for an attacker to guess valid credentials, potentially leading to unauthorized access or a denial of service.

A flaw was found in the Expat XML parsing library. A remote, unauthenticated attacker can supply a specially crafted XML document to trigger quadratic algorithmic complexity in the storeAtts() function, causing excessive CPU consumption and a denial of service
A flaw was found in Vim, an open-source command-line text editor. An attacker could craft a malicious tags file that, when processed by Vim's C omni-completion feature, leads to insufficient escaping of input. This vulnerability allows for the execution of arbitrary Ex commands and, subsequently, operating-system commands on the user's system. Successful exploitation requires a user to open a C file from an attacker-controlled tree and invoke C omni-completion on a member access whose type is resolved from the malicious tags file.
A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition (DTD) with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callback handler, where a string is freed twice. This flaw can lead to a denial of service (DoS) due to a reproducible crash in Python applications using the libxml2 SAX bindings.
A flaw was found in glibc. A remote attacker could exploit this vulnerability by providing specially crafted input during SHIFT_JISX0213 to UCS-4 text conversion. This crafted input can cause the application to repeatedly emit a buffered code point without consuming further input, leading to persistent retry churn. This can result in a denial of service (DoS) for callers converting untrusted text.
A flaw was found in glibc. Converting crafted EUC_JISX0213 input to UCS-4 or the internal wide character encoding (for example with iconv) can cause the converter to make no progress, hanging the calling application. Some EUC_JISX0213 sequences decode to two code points; if the output buffer has room for only the first, the second is stored in conversion state and returned as E2BIG, but that pending character is never cleared after it is emitted on the next call, so retries loop forever without consuming further input.
A flaw was found in OpenSSL. The Datagram Transport Layer Security (DTLS) retransmission mechanism fails to properly handle handshake message writes that are suspended before completion. A remote attacker could exploit this vulnerability during handshake message retransmission, causing OpenSSL to read past the message buffer or overwrite internal state required to resume writing. This issue can result in information disclosure through out-of-bounds memory reads or cause a Denial of Service (DoS) by crashing the process.
A flaw was found in libxml2, a software library for parsing XML documents. An integer overflow within the `xmlDictAddQString` function can lead to a heap-based buffer overflow. This vulnerability could allow a local attacker to execute arbitrary code on the system, potentially compromising its integrity and confidentiality.
A flaw was found in libxml2. A local attacker could exploit a stack-based buffer overflow in the `xmlSnprintfElements` function to achieve arbitrary code execution. This vulnerability in a fundamental system library could lead to significant system compromise if successfully exploited.
A flaw in libxml2's xmlXPtrEvalXPtrPart function allows a local attacker to cause a heap-based buffer overflow. An integer overflow while processing an oversized xpointer() expression leads to incorrect memory allocation and an out-of-bounds write, potentially resulting in information disclosure, data corruption, or a denial of service (DoS).
An integer overflow in the libxml2 xmlIO module occurs when data backlogs exceed maximum integer limits. This flaw passes negative length values to downstream write callbacks, creating an unsafe state that can lead to data corruption or compromise application confidentiality and integrity.
A flaw in libxml2's XInclude processing (xmlXIncludeProcess and xmlXIncludeProcessTree) fails to propagate parser flags like XML_PARSE_NONET. This allows custom resource loaders to fetch external network resources, potentially enabling Server-Side Request Forgery (SSRF), XML External Entity (XXE) injection, or Denial of Service (DoS) attacks.
A flaw was found in PCRE2. An out-of-bounds write vulnerability exists in the `pcre2_dfa_match` function due to improper size checking when reusing cached workspace blocks. A remote attacker could exploit this by providing a specially crafted regular expression or a recursive pattern in conjunction with a small heap limit. This could lead to data corruption or potentially arbitrary code execution, compromising the integrity and availability of the system.
A flaw was found in PCRE2. An attacker can provide invalid UTF (Unicode Transformation Format) data, leading to an out-of-bounds read during a Just-In-Time (JIT) fallback. This vulnerability could potentially result in a denial of service.
CWE-125 - Out-of-bounds ReadA flaw was found in PCRE2. On 32-bit platforms, an attacker can provide a specially crafted large pattern, leading to an out-of-bounds write within the pcre2_pattern_convert function. This vulnerability can result in high integrity impact, such as data corruption, and potentially a low availability impact, causing a denial of service.
A flaw was found in PCRE2. On 32-bit platforms, an integer overflow in the `pcre2_compile_32` function can lead to an out-of-bounds write. This vulnerability could allow a remote attacker to achieve a high integrity impact and a low availability impact, potentially leading to data corruption or denial of service.
A flaw was found in PCRE2, a library for processing regular expressions. A remote attacker could exploit this vulnerability by providing a specially crafted input that triggers an out-of-bounds read during pattern matching with invalid UTF (Unicode Transformation Format) characters. This could lead to a denial of service, making the affected system or application unavailable.
CWE-125 - Out-of-bounds ReadA flaw was found in PCRE2, a library for processing regular expressions. The `pcre2_jit_match` function, which handles just-in-time (JIT) compilation for regular expressions, incorrectly manages memory when processing certain inputs. This memory corruption vulnerability could allow a local attacker to cause the application to crash, leading to a denial of service, or potentially execute unauthorized code.
A flaw was found in Expat. This vulnerability allows a remote attacker to send specially crafted UTF-16 encoded XML data. Due to improper validation of surrogate characters, the parser can be tricked into accepting malformed sequences, which can hide legitimate markup characters. This could enable XML injection attacks, potentially leading to information disclosure or other integrity impacts.
A flaw was found in sudo. When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with timestamps that omit the trailing 'Z' timezone indicator, the time evaluation relies on the TZ environment variable inherited from the calling user. Because sudo is a setuid-root program, an unprivileged local user can set TZ to an extreme timezone offset to shift the authorization window by up to approximately 25 hours, causing expired rules to be treated as valid. This allows the user to execute commands outside the intended time window. Authentication is not bypassed; only the time-based authorization check is affected.
A flaw was found in pcre2. When an application processes attacker-controlled regular expressions using certain Just-In-Time (JIT) compiler interfaces, an out-of-bounds write with arbitrary data can occur. An attacker could exploit this vulnerability to achieve arbitrary code execution, corrupt memory, or cause a denial of service (DoS).

When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with timestamps that omit the trailing \u0027Z\u0027 timezone indicator, the time evaluation relies on the TZ environment variable inherited from the calling user. Because sudo is a setuid-root program, an unprivileged local user can set TZ to an extreme timezone offset to shift the authorization window by up to approximately 25 hours, causing expired rules to be treated as valid. This allows the user to execute commands outside the intended time window. Authentication is not bypassed; only the time-based authorization check is affected.",

Exploitation requires a sudoers rule with NOTBEFORE or NOTAFTER timestamps that omit the trailing \u0027Z\u0027 suffix, and the attacker must be the subject of such a rule. This is an optional feature not enabled in default configurations. PAM authentication is unaffected; the attacker cannot gain access beyond what the sudoers rule already grants. Sudo calls unsetenv(\"TZ\") and tzset() early in startup as a partial defense, but upstream accepted and fixed the vulnerability, indicating this control is insufficient on at least some platforms.
